RIVET AND BUTTON ATTACHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 450,828, dated April21, 1891.

Application filed May 24, 1890. Serial No. 353,032. (No model.)

To all whom it may concern:

Be it known that we, IRVING G. PLATT and FRANK R. WHITE, citizens of theUnited States, and residents of W'aterbury, in the county of New Havenand State of Connecticut, have invented certain new and usefulImprovements in Rivet and Button Attaching Machines, of which thefollowing is a specification.

IO Our invention relates to an improvement in rivet and button attachingmachines, the object of the same being to improve upon the constructionand arrangement of the fastening devices as now constructed and employedin machines of this character, and to provide devices for this purposewhich will be more certain in their operation of attaching the buttonsthan has heretofore been the case.

A further object of our invention is to pro- Vide a machine of thischaracter which shall be simple in its construction and arrangement ofparts, which shall be easily and readily operated and understood byunskilled persons, and which will at every operation of 5 the machineattach the button and rivet with certainty, which will not be liable toeasily get out of order, and so constructed and arranged that theseveral parts of the attaching mechanism may be readily and nicely ad- 3justed. \Vith such ends in View ourinvention consists in certain novelfeatures of construction and combination of parts, as willbe hereinafterfully described, and set out in the appended claims.

In the accompanying drawings, Figure I is a view in side elevation of aportion of abutton-maehine having attached thereto our improvedfastening mechanism. Fig. II is a longitudinal sectional view thereof onthe line a; m of Fig. III. Fig. III is a horizontal sectional view takenon the line y y of Fig. II.

Fig. IV is a similar view showing the parts in their adjustment afterthe plunger has been depressed. Fig. V is a horizontal sectional view onthe lines .2 of Fig. II. Fig. VI is a front sectional view taken on theline ,2 z of Fig. III. Fig. VII is a similar View after the plunger hasbeen partly depressed or lowered. Fig. VIII is asimilar View showing theparts in their several adjustments after the plunger has been lowered.Fig. IX 1s a detail View of the cam employed to open or Separate thereceiving-jaws.

0 ur in vention, as will be hereinafter learned, belongs to that classof devices for attaching buttons and rivets contemplating the use of arotatinghopperA,intowhichtherivetsortacks are fed in bulk, and fromwhich they are led to the attaching device by means of a twisted chuteB, into which they are fed point up and head down, and from which theyescape into the receiving-jaws head up and point down, and which classof machines also contemplates the use or employment of mechanism forrevolving said hopper and the ordinary form or construction of cut-offB. The ma chine is also provided with a main frame A, consisting of acurved supporting-arm a and the base or bed plate Z), to whichsupportingarm a is attached the 0perating-leverA and which in turn hasconnected therewith the vertically-reciprocating plunger A working orsliding in the barrel or cylinder a, formed on the supporting-arm a ofthe main frame.

As those parts of the machine above referred to are of the ordinaryconstruction and arranged to operate in a manner which is wellunderstood by those skilled in this art, it is not deemed necessary todescribe in detail their construction or arrangement.

The curved arm a of the frame is provided with the bifurcated arm 00*,between the prongs of which fits the twisted chute B, which is heldthereby against all lateral movement, but which arm allows of a downwardand backward movement of the chute in case a rivet or tack shouldaccidentally become wedged between the plunger and the chute.

'As shown by Figs. 3 and l of the drawings, the lower rear portion ofthe curved arm a of the frame is provided with an elongated slot oropening to, in which is mounted or pivot-ed one end of the arm 0, theforward end of which is flattened or widened into the form of a plate,as shown at d, the object or purpose being to form or provide a supportfor the attachment of the rivet-receiver, which consists of the two arms(1, having their rear ends attached to said plate or support (I by thecommon pivot d and connected and retained in their proper position bymeans of the spring E. The ends of the said two arms d are extended to apoint directly below the plunger A and cup-shaped in form, as shown at dfor the purpose of receiving a rivet or tack from the lower'end of thetwisted chute or raceway leading directly thereinto and holding saidtack in position to be operated,

upon by the plunger when the latter is lowered.

To the plate (Z and between the arms (1 of the receiver is secured bymeans of a screw 6' the sleeve or cam F, fitting around said screw e andhaving its sides flattened, as shown at 6 against which flattened sidesbear the inner sides of said arms (1 when the latter are in their closedposition for receiving a rivet from the raceway. This cam is formed onits upper end and at one side with ahandle 6 by which it may be turnedupon the pin or axis e, the object and effect of which is to open orseparate the arms d and cup (1 and release or allow the escape of therivet or tack therefrom when desired to remove it, the spring Ereturning the arms 01 to their normal position upon releasing the handle6 of the cam.

The arm 0, with its attached spring-actuated receiver, is supported inits normal or substantially horizontal position (in which po sition thecup or receiver 62 is held up against the lower end of the raceway orchute B) by means of the rod or bar f, which passes through said arm 0and threaded therein, and is secured in its several vertical adjustmentsby means of the lock-nut f, the lower end of said pin, which projectsbelow the arm 0, resting upon the head or upper end of the plug f whichis nicely fitted within the cylinder or barrel f formed on andprojecting above the bed-plate b, said plug resting or being seated upona coil-spring f titted in the cylinderf the object of this constructionand arrangement of parts being to allow a downward or vertical movementof the arm (3 and its attached receiver, and upon the release of thesaid arm to return the latter to its original horizontal position, thearm, after having been raised to its proper height by means of saidspring, striking or abutting against the set-screw g, threaded in areceptacle or sleeve 9 formed on and projecting downwardly from thesupporting-arm a, said set-screw, after being raised or lowered to itsproper adjustment to determine the proper height to which the said arm 0is to be raised, being locked in such adjustment by means of thelock-nutg It will of course be understood that by raising or loweringthe pin or barf and the set-screw g the arm 0 will be correspondinglyraised or lowered and the extent of its vertical movement or travelcorrespondingly limited or enlarged. It is obvious that, if desired, thearm 0, with its receiving-jaws, may be held stationary, the arm havingbeen first so adjusted that the point of the tack or rivet will enterthe goods before being entirely forced out of the receiving-jaws d d bythe plunger.

In the slot 00, formed in the lower rear end of the supporting-arm a ofthe frame and below the pivotal connection of the arm 0. is

pivotally secured a lower or second horizontal arm 0', which is widenedand flattened at its forward end to form a support or base It for theplates h h, each of which latter is pivoted at its rear end, as shown at71?, to the arm 0, and are held in their proper relative position bymeans of a spring g the forward ends of said plates being arranged toseparate and extend out beyond the forward end of the arm 0 and belowthe cup (1 formed on the forward ends of the arms 61', secured to thearm 0.

The spring-actuated plates h h are provided with the opening g in theirforward ends to permit. of the entrance of the tack, as hereinafterdescribed, the sides of said opening beingpreferably beveled for thepurpose of properly guiding the point of the tack through the saidopening, and is formed in the same vertical line with the opening in thecup 01 The arm 0' is also widened near its rear end in order to providesufficient material to allow the opening 71 to be formed therein, thelatter intended and serving as an opening or passage for the post f andplug f to permit of their vertical movements withoutinterfering with themovement ofthe arm 0. The rear ends of the said yielding plates are cutaway at a slant, as shown at h, for the purpose of allowing their freeforward ends to be separated or spread apart, said rear ends of theplates striking or impinging against. the fin or flange 9 formed on theupper side of the arm 0' after the forward ends of said pivoted plates h72/ have been separated to their fullest extent.

The arm 0' is held in its normal or substantially horizontal position bymeans of the sliding rod or bolt 1'', on the upper end 2' of which saidarm rests, and which end is also provided with a head or flange 2'against which fits the upper end of the coiled spring '5 the lower endof said spring impinging against a shoulder formed around the opening imade in the base-plate b,- and in which opening reciprocates the rod i,the lower end of said latter rod extending out through said opening andprovided with a thread on which is fitted the nutj. It will beunderstood from this construction and arrangement of parts that afterthe arm 0 with its attached spring-actuated plates has been lowered bymeans of the plunger and released, as hereinafter described, the coiledspring '0'" will return the rod 2" and arm 0 to their original position,the height to which said arm is raised .being regulated by means of thenut j, by raising which the rod will be virtually shortened, and bylowering which the rod will be lengthened, and the height to which saidarm 0 is raised being correspondingly regulated.

To the forward end of the base-plate b is attached the yieldingbutton-support 7c, constructed and arranged as followsz-The forward endof said base-platebis provided with a threaded opening 76, in which isfitted the thumb-screw 7%, having tightly secured thereto the anvil 76The upper end of the thumbscrew k projects through and above thebaseplate I), and has fitted thereon the circular nut 71: provided Witha shoulder against which fits one end of thecoiled spring 7c, the upperend of the same fitting against the under side of the button-support 7c,the hollow shank of which fits down within the hollow nut and around thedie or anvil 753, the shoulders 41/11: being formed on the nut and shankof the support, for the purpose of preventing the parts from becomingseparated or disengaged. It will now be understood that when the support7; is pressed downwardly by means of the plates h h, the upper end ofthe anvil or die 712 is exposed, and when released will be raised orreturned to its original position by means of the coiled spring 7t, theheight of said anvil or die it being regulated by raising or loweringthe thumb-screw 79.

On the lower side and near the forward ends of the plates 7t h areformed the downwardly-projecting lugs or shoulders Z Z, the inner sidesor edges of which are beveled, as shown at Z, and which, when the arm 0with its plates are lowered, strike against the up per beveled edge Z ofthe button-support 7c, the effect of which is, when the plunger isforced downwardly, to open and separate said plates and force the latterdown upon the upper side of said support 7e, and, the plunger beingcontinued downwardly, to carry said plates downwardly, and, by reason oftheir bearing upon the button-support, to carry the latter downwardlyuntil the upper end of the anvil or die if is exposed, as beforedescribed, the plates It It being returned to their original position bymeans of the spring after the plunger is raised, the arm 0 at the sametime being returned or raised, with the attached plates, by means of thecoiled spring To the under side of the arm 0' is secured by means of thethumb-screw Z the adjustable gage Z having its forward end widened inorder to allow of the separation of the plates h h, and provided withflaring lugs Z said gage being provided on its under side with anelongated slot for the purpose of allowing said gage to be movedforwardly or backwardly in order to regulate the extent to which thefabric is inserted in the machine, and thereby enabling the buttons tobe placed in their proper positions.

Having now fully described the construction and arrangement of theseveral parts of my improved machine, I will proceed to describe themodus opemmli. Asis well understood, the chute and the cut-offarrangement allow a tack or rivet to drop or fall into the receivers d.The gage having been properly set and a button having been placed inposition upon the support 7c, the fabric is placed upon the plates 7L h.The plunger is then forced downwardly upon the head of the rivet, which,with the arm C with its attached recelver, is carried downwardly by theplunger until the lower end of the plug f 3 strikes the bottom of thecylinder f at which time said arm 0 and its receiver have reached thelower arm 0' and the point of the tack or rivet entered, or about toenter, the fabric placed thereon. The plunger being continueddownwardly, the jaws d are forced open and the rivet forced out of thecup or receiver (Z into and through the fabric, said jaws partiallyencircling the plunger and being returned with the arm 0 to theirhorizontal adjustment by means of the spring. The plunger, being stillcontinued or forced downwardly and bearing upon the head of the rivet,carries the latter, with the plates h h and the arm C and the fabricplaced on said plates h h downwardly until the beveled lugs Z Z strikeagainst the upper beveled edge Z of the button-support 70, at which timethe said plates will open or separate, as before described, and theseveral parts then be carried downwardly by the plunger until the pointof the rivet has passed through the fabric into the opening in thecenter of the button and has been upset by striking on the die, thelower end of the plunger being recessed, as shown at :0 for containingthe head of the rivet, which materially assists in holding the rivet inits vertical position and causing it to properly en ter the opening inthe button and button-sup port. The plunger is then allowed to rise, andthe fabric with the button secured re moved from the yielding plates 7t72/ and the parts allowed to return to their normal position by means ofthe several springs, as hereinbefore described. The operation. may thenbe repeated.

What we claim is 1.
